I concur...
I definitely agree with Mr Newsome regarding your waistcoat. I also like to wear vests or waistcoats without a jacket, and they tend to look better (I think) when they are buttoned, especially with a tie. And then of course you dont need the belt. Kudos on the waistcoat and tattersall shirt- very smart, and British! 
You should also check out the "Weathered" hunting and regular McIntosh tartans. I think they look REALLY cool. My Momma is a Kentcke McIntosh, so those are two tartans that I am seriously considering for my next Matt Newsome kilt!
Cheers,
Wesley

I think an open vest looks good with a less formal outfit (no tie). Oddly enough, I do think that a belt looks fine when worn with an open vest.
The only other suggestion is that I think a brown leather sporran would look stunning -- it would tone well with the vest, the shirt, and the tartan.
Great looking tattersal shirt, by the way!
